This adds the ability to format f2fs and ext4 in a way that supports casefolding and project quotas. Project quotas require wider inodes, and thus cannot be enable apart from at build time. Casefolding can be configured with f2fs.fsck/tune2fs later. Both features are enabled via inheriting emulated_storage.mk in the device.mk Bug: 138322712 Bug: 138321217 Test: Enable on device with related patches, view fs configuration on /data Change-Id: Ib1ab0589006ff1b3fb7478b7e9b0a8aad71e4b09
Android Make Build System
This is the Makefile-based portion of the Android Build System.
For documentation on how to run a build, see Usage.txt
For a list of behavioral changes useful for Android.mk writers see Changes.md
For an outdated reference on Android.mk files, see build-system.html. Our Android.mk files look similar, but are entirely different from the Android.mk files used by the NDK build system. When searching for documentation elsewhere, ensure that it is for the platform build system -- most are not.
This Makefile-based system is in the process of being replaced with Soong, a new build system written in Go. During the transition, all of these makefiles are read by Kati, and generate a ninja file instead of being executed directly. That's combined with a ninja file read by Soong so that the build graph of the two systems can be combined and run as one.
